Inflection transducers

An inflection transducer describes the morphological variation that is associated with a word class by assigning inflectional codes to each variant. The paths of such a transducer describe the modifications that have to be applied to the canonical forms and the corresponding outputs contain the inflectional information that will be produced

LADL

Lexicon-grammar is a methodology developed by Maurice Gross and the LADL team ([9], [10], [38], [51], [49], [50], [48], [47], [44], [43], [42], [41], [40], [64], [83]) based on the following principle: every verb has an almost unique set of syntactical properties. Due to this fact, these properties need to be systematically described, since it…

Latent Dirichlet Allocation

LDA is a generative probabilistic topic model. It represents the documents as a random mixtures of topics over the latent topic space, where each topic is characterized by a distribution over a dictionary of words. LDA and its extensions are ineffective when used with short documents (texts). Issues are coming from: ineffective word relation induction…

Latent Semantic Indexing/Analysis

The Vector Space Model, document representation method, doesn’t give the semantic relations of term. The LSI method overcomes the limitation of VSM. LSI is an approach that use particular matrix transformation technique called Singular Value Decomposition (SVD).
